1. What is the wavelength of a radio wave broadcast at 150 MHz?
Answers
The value of the wavelength will be equal to 2 meters.
It is given that a radio is broadcasting at 150 MHz .
We have to calculate the wavelength.
What is the formula for wavelength ?
The wavelength is given by L = c/f , where c = speed of wave and f is the frequency of wave.
∵ L = c/f
Let's assume c = 3 × 10^8
Given that frequency (f) is 150 MHz .
Wavelength (L) is approximately ;
L= (3 × 10^8 )/ (150,000,000)
L= 2 meters
Thus, the wavelength of a radio wave broadcast at 150 MHz will be equal to 2 meters.

On a coordinate plane, a curved line with a minimum value of (5.1, negative 7) and a maximum value of (0, 25), crosses the x-axis at (negative 3.4, 0), (3.9, 0), and (6, 0), and crosses the y-axis at (0, 25).
Which statement is true about the local minimum of the graphed function?
Over the interval [–4, –2], the local minimum is 0.
Over the interval [–2, –1], the local minimum is 25.
Over the interval [–1, 4], the local minimum is 0.
Over the interval [4, 7], the local minimum is -7.

Answer:
D
Step-by-step explanation:
The rest of the question is the attached figure and the statement options.
A. Over the interval [–4, –2], the local minimum is 0.
B. Over the interval [–2, –1], the local minimum is 25.
C. Over the interval [–1, 4], the local minimum is 0.
D. Over the interval [4, 7], the local minimum is -7.
============================================================
According to the graph, we will check the options:
A. Over the interval [–4, –2], the local minimum is 0. (Wrong)
Because the minimum is -12
B. Over the interval [–2, –1], the local minimum is 25. (Wrong)
Because the minimum is 18
C. Over the interval [–1, 4], the local minimum is 0. (Wrong)
Because the minimum is at x = 4 less than zero
D. Over the interval [4, 7], the local minimum is -7. (True)

Of the 50 students in the cafeteria, 7 have red hair. Suppose there are 750 students in the school. Write a proportion that could be used to predict the number of students who have red hair. Use x to represent the number of students who have red hair.
Answers
Given:
Of the 50 students in the cafeteria, 7 have red hair.
Total number of students = 750
To find:
The proportion that could be used to predict the number of students who have red hair.
Solution:
Let x represent the number of students who have red hair.
The ratio of student having red hair to the total number of students are
[tex]Ratio_1=\dfrac{7}{50}[/tex]
[tex]Ratio_2=\dfrac{x}{750}[/tex]
The number of students having red hair is proportional to the total number of students. So, the above ratios are equal.
[tex]\dfrac{x}{750}=\dfrac{7}{50}[/tex]
Multiply both sides by 750.
[tex]\dfrac{x}{750}\times 750=\dfrac{7}{50}\times 750[/tex]
[tex]x=7\times 15[/tex]
[tex]x=105[/tex]
Therefore, the required equation is [tex]\dfrac{x}{750}=\dfrac{7}{50}[/tex] and the number of students who have red hair is 105.

You are a screenwriter who is writing a script for an hour-long police drama. You have written 20 1/2 pages for act 1 and 5 1/2 pages for act 2.
How many pages have you written in total?
Answers
Answer:
You have written 26 pages in total.
Step-by-step explanation:
I always enjoyed adding fractions. Something about it is so... simple.
The problem is basically asking us to add 20 1/2 and 5 1/2 together.
I would first suggest adding both halves together, to make 1.
That way, we're left with 20 + 5 + 1. That seem easier, doesn't it?
Then we would add 20, 5 and 1 together, to get 26 whole pages.
And that, to an extent, is how I did it.
Hope this helps! :D
Answer:
Given:
Written pages for Act 1 = 20 1/2
Written pages for Act 2 = 5 1/2
For making mixed numbers like this easier to add, let's convert them first into an irrational number with this formula,
((Whole Number × Denominator) + Numerator)/Denominator
Thus,
for 20 1/2
((20 × 2) + 1)/2 = 41/2
for 5 1/2
((5 × 2) + 1)/2 = 11/2
Then we add,
41/2 + 11/2
Since, they have the same denominator, no more conversions need, proceed adding the numerators,
(41 + 11)/2 = 52/2 = 26
You've written 26 pages in total.

The scale of a map says that 2 cm represents 10 km. What is the actual number of kilometers that is represented by 6 centimeters on the map?
Answers
Answer:
6 times 10 to the minus 5
6 cm on the map represents 30 kilometers in reality, with a scale of 2 cm representing 10 km.
In the given map, the scale is 2 cm represents 10 km.
Each centimeter on the map represents 5 km (10 km divided by 2 cm).
We can use the scale of the map, which states that 2 cm represents 10 km, to determine the precise number of kilometers that 6 centimeters on the map represent.
If 2 cm represents 10 km, then 1 cm represents 10 km / 2 cm = 5 km.
6 centimeters on the map represent 6 cm × 5 km/cm = 30 kilometers in reality.

Explain how to use the distributive property to find the product 3 x 4 1/5
Answers
Answer:
12.6
Step-by-step explanation:
The answer is 12.6 and here is the explanation of using the Distributive Property. Because we are multiplying a whole number by a mixed number, we have to multiply the whole number by the whole number in the mixed number and then multiply the whole number by the fraction. In this case, we have 3 x 4 1/5. We multiply 3x4=12 first, and then we multiply 3x1/5 to get 0.6. 12+0.6=12.6. Hope it helps!
The product of 3 x [tex]4\frac{1}{5}[/tex] is 12.6.
What is Number system?A number system is defined as a system of writing to express numbers.
The distributive property tells us how to solve expressions in the form of a(b + c).
The given expression is 3 x [tex]4\frac{1}{5}[/tex]
This expression can be written as 3(4+1/5)
The value of 1/5 is 0.2
